    PFMEA (Process FMEA) - Can be common for 3000 products?

    Hello all, We're producing plastic injection parts (nearly 3000 different types of products) and it's impossible to track their PFMEA and Control plan. So, I'd like to know if it's possible to make a common PFMEA for every step of process, such as; 1. Receiving Inspection FMEA 2. Material...

    Process disturbances and the repair - How do you handle this risk in your company?

    If we create the P-FMEA the PFC is our input. In our process flow, we donˋt describe process disturbances and the repair. How do you handle this risk in your company? Is there a clear recommendation, how this could be covered, or should this excluded from the risk analysis? Thanks for your replay!

    DFMEA/PFMEA and SCCAF alignment

    Hello everybody, I work as a quality engineer for the past year and I am very much interested in DFMEA/PFMEA and SCCAF The engineers where I work are unable to tell me the following: 1 ) should DFMEA and PFMEA be aligned in terms of SC and CC (Significant and Critical Characteristics). When I...

    Control plan evaluation methods - Which methods should be carried over from the PFMEA?

    Hi greetings!! I'm new to control plans and I haven't had much luck finding good literature about it. So I have this question: In the evaluation methods column which methods should be carried over from the PFMEA? The detection methods or the prevention methods? also, can this column have...

    PFMEA - How long should the recommended actions remain in the recommended actions column?

    How long should the recommended actions remain in the recommended actions column? The person who updates our PFMEA's doesn't ever want to remove them. So there are actions listed from 2 years ago. We are doing an annual validation PPAP and he's updated the PFMEA but he wants to keep it there...

    Informational Family or Baseline PFMEA Rules

    Can anyone help me to understand the proper use of a family or baseline PFMEA? I'm in a very heated debate on the proper use of a family or baseline PFMEA with my Quality Engineer and Quality Manager. We had an internal auditor (3rd party) tell us it's ok to submit a "family process FMEA" that...

    PFMEA severity score different applications

    Hi All, how to manage multi customer applications for the same process in terms of severity scoring. E.g The product produced may go into a safety critical application and score a severity of 9 or a non safety application and would score eg 4. The product goes down the same process but multi end...

    Sequence of Process Steps not Respected

    How would you use FMEA to ensure proper sequence of steps? At the moment PFMEA studies the failure modes associated with each steps, but we found ourselves confused when somebody did the steps perfectly, just not in the right order. How would you tackle this? Let's imagine a station in which...

    Control Method correspondence between PFMEA and CP

    Hi everyone, I am looking forward for your input. It is said (as per AIAG) that there should be correspondence between the PFMEA and CP in regards of the "control methods" for all characteristics (which has failure modes, effects and causes associated). Before expressing my approach, I want to...

    In-Process Production Test Stations in PFMEA (Process FMEA)

    Hi all greetings. Working in one of my first PFMEAs I come across with tester stations. My question is how are these stations treated? They are part of the process but no operation is being made, or modifications are being made to the product they are just testing some characteristics of...

    DFMEA / PFMEA linkage - Where in the standards do I find it?

    Is there any requirement (current or upcoming) for suppliers to have access to customer's DFMEA in order to complete their PFMEA? I know it's a "best practice", but not all customers are willing to share them. If so, where in the standards do I find it?
